Really don't want to tear up the threads wrenching them in.

Zeus cranks could be had in either metric (14mm x 1.25) or BCS (9/16" X 20TPI) thread. The back of a BCS-thread arm will be marked "BCS" while a metric thread arm will be unmarked.

N.B. a metric thread arm can easily be re-tapped to BCS thread.
